Synthesis of 1,2,4-triazole derivatives containing benzothiazoles as pharmacologically active molecule

摘要

In attempt to make significant pharmacologically active molecule, we report here the synthesis and in vitro antimicrobial and antitubercular activity of various series of 3-(3-pyridyl)-5-(4-nitrophenyl)-4-(N-substituted-1,3-benzothiazol-2-amino)-4H-1,2,4-triazole. The antimicrobial activity of title compounds were examined against two Gram-positive bacteria (Staphylococcus aureus, Streptococcus pyogenes), two Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa), and three fungi (Candida albicans, Aspergillus niger, Aspergillus clavatus) using the broth microdilution method and antitubercular activity H₃₇Rv using Lowenstein-Jensen agar method.
